Thank you for the wonderful pointer to good information. When I
was writing my PhD in 1966, there was little if anything known
about the condition mumbers. Your judiciously chosen references
put me on the track to search some information about it.
Internet is wonderful - there are some well written material
there to keep me quietly reading for a while...
